EA RL ROBERT SCOTT, 0F LUEDERS, TEXAS.

INSECT-EXTERMINATOR.

Application filed October 9,

Toall whom it may concern Be it known that I, EARL ROBERT Sco'rr,

Lueders, in the county of Jones and State of Texas have invented certain new and useful Improvements in Insect-Exterminators, of which the following is a specification:-

This invention relates to insect exterminators andmore particularly to that class of machines adapted to brusli'boll weevils from crushed automatically, and has for its object to provide an attachment which can be quickly attached to or removed from a cultivator of usual construction. I The invention consists broadly in providing laterally and vertically adjustable brushes for removing the insects from the plants, whereby the brushes may be readily adjusted to suit plants of dilferentheight or rows of varying distances apart. 0

. In the drawings: Figure 1 is a side view of my invention attachedto a cultivator of any well known construction. Fig. 2 is a plan view. Fig. 3 is a fragmentary front view of the frame supporting the roller wheels-42. Fig. 4 is a front view of the frame supporting the front brushes 32 one. of the arms 22 being removed.

Referringmoro particularly to the draw ings in which like reference, numerals refer to corresponding parts throughout the different views 5 designates the rear wheels of a cultivator mounted to rotate with an axle 6. Suitable uprights or posts 7 are sup ported. from the ends of theaxle 6. and simisuitable manner at the opposite or front end of the cultivator. Cross bars 8 (only one bar shown) connect theposts of each pair and constitute supports for a central longitudinally-extending bar 9 which preferably openings in whichtheends of a shaft 11 are journaled. The shaft 11 has a belt wheel 12 and a small at 13 fixedly secured thereto the latter being positioned to mesh with a connected to a pulley or belt wheel 15 by A bracket or yoke 17 adjustably secured to the bar 9 by means of set screws 18 forms a bearing fora hollow shaft 19 to whichthe pulley or belt wheel 15 is fixed and in the Specification of Letters Patent.

telescopically and adjustably inserted. Set screws 21 secure the shaft 19 and extensions '20 in any desired adjusted position.

Adjacent the bracket 17 and slightly to the rear thereof is a pair of depending divergingly curved arms Secured at their upper ends to the bar 9 by means of set formed thereon andare rotatably supportedin brackets 28 attached to extensions -20.

'This construction permits of the extensions 20 and one end of brushes 32 being forced away from or drawn toward the bar 9 without disengaging gear 2'? from gear 29 on the end of extensions 20. l

33 represents a hollow arm supported from the bar Qby means oi a yoke 34 slidably mounted for longitudinal movement on said barp Short extensions terminating at. their ends in hollow tubular enlargements 36 are loosely inserted in the ends of the h0llow arm 33 and adjustably retained therein by means of set screws 37. A rod 38 adjustably secured within each tubular enlargement 36 carries a yoke 39 the," ends of which carry split sleeve bearings 40 in turn forrmin a ournal for the hollow axles or shafts ened as occasion requires and in a manner hereinafter explained.

A yoke 47 similar to the yoke 34: and secured to the bar 9 by means of set screws or bolts 48 supports a tubular sleeve 49 extending on either side of and beneath the bar 9. ort tubular extensions 50 similar to the extensions 35 (previously described) are secured within the ends of the sleeve 49 by means of set screws 51.. and rods 52 have their upper ends secured in the tubular enlargcments 53 of extensions 50 before mentioned. The lower ends ofthese rods 52 are provided with sockets 5 adapted. totorm a tXl'GliFlull and conseiuiently the shafts in position to retain the small beveled gear oi on extension .36 in mesh. with the large beveled ear ($1 on extensions &6. Brushes (i?- of an suitable or Well known constructionarc ured to the shafts in practice 'the machine is drawn between the rows of cotlon plants the forward brushes 32 being driven from the rear axle t3 and the rear brushes from the hollow axle ii on forward arheels 42. The last mentioned wheels also serve the function of depre sing a furrow to receive the insects rc nun-ed from the plants to the ground by the brushes "where they are brushed into a row by the hr: In this conner "ies 61?. tion it will be noted that the apex of the angle formed by theconverging brushes 6:2 in alineiuent with the vertical axles of aid Wheels Consequently the brushes ,tlilbrush the insects to the center of the furrow. As the machine proceeds the row of insec s thus brushed into the. furrow or depression made by the Wheels 42 are crushed by the rear wheels and thus completely destroyed.

The tor-ward brushes 32 can be readily l 'l to suit )laut' or". diilerentin ui oi ouhi 1 5 heights by simply loosening set screws 18 and and raising or lowering the yoke 17 and arms 22 as desired.

I ll'hen ii is desired to spread the brushes he set screws- 4;? and..-it8 are loosened and thc bolts .33 remov dfrom yolie -51,- Wheream the yolic (i-Band the entire ujicchanisni ill 1 rilPiHnl 'ad Iherch v {nu-hiding hollow shalt 'll. wheels -51! and rods may be moved l ngitiuiiuall upon the bar 5). This more 1 66, and extensions 67 and 68 secured in the ends of thesesleeves by set screws 69. Le.- rers 70 and 71 mount-ed respectively on the ends of extensions 67 and 68 have their free ends connected to the upper ends of link rods 7; and T 5 attached at their lower ends to the rods 38 and 52. A connecting link 7 connects the two projections T5 and T6 on sleeves 6i and respectively and an operating lever 77 on sleeve 6i affords means for simultaneously rocking the levers T0 and-Tl to raise or lower the brushes From the foregoingit will be seen that both the forward and rear sets of brushes can be readily adjusted in either a vertical or latera]. direction without disconnecting the driving mechanism.

Having thus described my in vention what. I claim is:

- l. In a machine oi the class described a support, a pair of brushes suspended from said support, a second pair of brushes suspended from said support and means to! raising and lowering said last named pair of brushes.

'2. In a machine of the class described a support, a sel. of brushes suspended from said support, said brushes being inclined forwardly from the vertical plane, means for raising and lowering said brushes, :1 sec-- ond set of brushes suspended from said support, means for raising and lowering said second of brushes. and means for independently rotating both sets of brushes In machine of the class described, a support, a plurality of pairs of horizontally arranged brushes carried by said support, said brushes being arranged in pairs inclincd rearwardly in a converging direction, means fl 1 altering the angle of inclination of said brushes, means for raisiuq and low ering one pair of said brushes independently of the other pair.

at. In a machine of the class described, a support. a pl urality of horizontally arranged brushes carried by said support, said brushes being arranged in pairs, inclined rearwardly in a converging direction, means for altering the angle ot inclination of said brushes, means For raising and lowering one pair of said brushes independently of the other pair, and in ans for simultaneously raising or lowering all of said brushes.

In testimony whereof I ailix my signature in presence of two witnesses.
